Calibration by Entry of Premeasured
Cell Constant
You can directly enter the cell constant of the cell
in use. Usually, the cell constant is printed on the
cell.
The specified cell constant varies due to the
manufacturing process. With some cells, it can
also change depending on the installation conditions.
For accurate measurements, you should
therefore calibrate each cell individually (Automatic,
Manual or Sampling).
The SE 604 ultrapure water cell must be calibrated
by direct entry of the cell constant since calibration
solutions in the S/cm range are not stable.
During calibration, output current (1 and 2) and
controller output are frozen, limit contacts are disabled,
the “probe” contact is enabled (only with
option 352).
How to enter premeasured data
